India Kids Fashion Show [IKFS] — Refund and not respond

Address:

Delhi

Hello sir / ma'am

On 25 Jan 2019 I had pay 2 daughters fee. But I was forget to take discount on that amount ( which is around 7 thousands).
They called me back. And said. "Take tickets with discount code. This money will be refund soon.."

Than. I had pay again 5 thousand for 2 daughters..

On that day I had pay almost 12 thousand rupees.

Since 3-4 months I call them .. n request them..to refund money . Which was submmitted without discount code...
They said yes ma'am we are doing...
Know they are not even picking the phone... Also not giving the information of the ongoing show which is going in delhi.
Pls sir/ ma'am

Resolve the issue.

Thanks
